Version of SCOOPS modified to work with MIT Scheme.

The scoops-7.0.scm in this directory modified by Peter Ross
(peter@aipna.ed.ac.uk) to work with MIT Scheme 7.0 and beyond. It is
based on a version of scoops written at Texas Instruments and modified
by sherin@linc.cis.upenn.edu (who is probably no longer at
linc.cis.upenn.edu) to work on an old version of MIT Scheme.
